Review on Pack of 50 Metal 'L' Bobbins - (55623S) - (SA159) - (H12413002) by Kelsey Brown

I sew for a living, I change bobbins all the time and sometimes it can take a very long time to thread the bobbins. Therefore, it is very convenient to have extra bobbins with threads of the same color. Pros: - Great product at a great price! in the middle to wind the bobbin. Cons: - The notches/holes on the spools are different sizes. I noticed that some can be a bit longer. I've posted a photo (see photo above, fig 1) showing the difference. From what I've noticed, those with a slightly longer notch wind up nicely in the winder. I found that two spools don't fit in the winder because the notch wasn't cut well :(. You can see a little on the bottom photo (fig 2) that the notch on the spool on the right wasn't cut very well compared to left.Overall I'm still happy with my purchase.
